Description
Technical field
The present invention relates to gas heater control technology field more particularly to a kind of permanent negative pressure gas heaters.
Background technique
Existing strong pumping combustion gas gas heater uses upper pumping DC fan, and in the external world, blocking causes gas heater to be discharged fume
When unsmooth, pressure reduction is burnt insufficient, and flue gas is exceeded, influences personal safety.To solve this problem, in the prior art greatly
Stopping state is all determined by the change of rotation speed of fan.However, there is drift in rotation speed of fan, and under the identical voltage of different blowers
Revolving speed it is also different, program will provide corresponding error, cause correctly judge to block.In addition, existing program only adopt by basis
Sample numerical value starts to add wind when revolving speed reaches existing numerical value, adds wind air quantity different according to chocking-up degree difference, passively to add wind,
The effect is unsatisfactory.
Summary of the invention
Aiming at the problems existing in the prior art, good the purpose of the present invention is to provide a kind of Wind-Pressure Resistance effect and anti-
It can be carried out the permanent negative pressure gas heater of normal work when wind pressure job failure.
To achieve the above objectives, the present invention adopts the following technical scheme that.
A kind of perseverance negative pressure gas heater, which is characterized in that initial according to one different negative pressure of different set of load
Value, the corresponding gas ratio valve electric current of each load, bears using in wind pressure sensor real-time detection gas heater cavity
Pressure value；When wind pressure sensor output is normal, gas heater carries out Wind-Pressure Resistance work, determines negative pressure according to gas ratio valve electric current
Initial value makes negative pressure in gas heater cavity using blower plus wind when negative pressure value changes in gas heater cavity
It is worth constant in the initial value；When wind pressure sensor output abnormality, shields wind pressure sensor and transmit signal, gas heater carries out just
Often work.
As a further illustration of the above scheme, the corresponding relationship of load and negative pressure initial value are as follows:In formula, P represents negative pressure value initial value, and Cur represents gas ratio valve electric current
Value, LO represent minimum negative pressure value when gas water heater working, and HO represents highest negative pressure value when gas water heater working, PH generation
Table gas ratio valve electric current peak, PL represent gas ratio valve minimum current value.
As a further illustration of the above scheme, passing through the operation of gas heater when wind pressure sensor output abnormality
Display issues wind pressure sensor abnormal prompt signal.
As a further illustration of the above scheme, the output of detection blower fan revolving speed is after shielding wind pressure sensor transmission signal
It is no normal；If it is, cleaning before blower operating, gas water heater ignition inhales valve, after detecting flare up fire, combustion gas heat
Hydrophone is worked normally；If it is not, then the operation display by gas heater issues blower abnormal prompt signal.
As a further illustration of the above scheme, one blower maximum speed of setting, when rotation speed of fan is more than maximum speed
When 5s or more, fault cues signal is issued.
As a further illustration of the above scheme, fault cues signal is icon flash signal or alarm standby signal.
As a further illustration of the above scheme, the blower is DC frequency-changing blower.
The beneficial effects of the present invention are:
When carrying out Wind-Pressure Resistance work, wind is actively added to maintain negative pressure in cavity constant, so that carbon monoxide content is not overweight.
Under different load, with the variation of extraneous wind pressure, carbon monoxide content UCO is held essentially constant, and guarantees combustion conditions, effectively
Unpleasant pernicious gas is avoided the occurrence of, comfortable for living is influenced.Particularly, when wind pressure sensor occurs abnormal, gas and hot water
Device remains to normal use, and issues wind pressure sensor abnormal prompt, convenient for maintenance in time.
